numbers 1 and 2; number 5 by notching both the number 4 and 1 perforations to the edge of the card; number 6 by notching the number 4 and 2 perforations to the edge of the card; number 8 by notching perforations 7 and 1 to the edge of the card; and number 9 by notching perforations 7 and "2 out to the edge of the card. In each instance, any number is either notched, or, in the event the digit in the field is to be designated as a 0, such field is slotted between the 0 and 1 numbers.

As an eir'amplathe number 309 is designated in Fig. 3, the numbers 2 and-1" perforations being notched to the edge 12 of the card, the next adjacent field being slotted between the 0 and 1 perforations, and the succeedingfield being notched to the edge of the card from the number 7 and number 2 perforations. Similarly, assuming that there are a total of four-fields along the edge of the card and that the number 30 is to be designated, the card would actually be both slotted and notched in thepattern of 0030, as represented in Fig. 4.

Thus, from the foregoing description, it is apparent that the digit 0 is indicated in a particular field by a slot 11 running between the 0 and 1 perforations. This mode of designating the number 0 is unlike the arrangements heretofore used, in which the number 0 is disregarded,'the particular field designating 0 by remaining free from notching or slotting. In the prior arrangements, sequence sorting could be performed readily with a card of the character indicated in the drawings, but selective; sorting could only be performed with great difficulty, since the selective sort was productive of a large number of selected cards which had to be visually removed from the actual cards desired. For example, in the prior arrangements the number 309, such as indicated in Fig. 3 in the drawings, would have been designated by the notched grouping in the first and third fields,but there would have been no notching or slotting in the intermediate field, thereby designating the number 0. Accordingly, attempts at selectively sorting all cards numbered 309 would'have been accomplished merely by passing sorting rods and needles through the number 2 and 1 perforations in the first field and the number '7 and '2 perforations in the third field. No sorting rods or needles would have been passed through'the intermediate field. Accordingly, all cards ranging from numbers 309 to 399 would have been selected by this type of sort, in view of the lack of any means for preventing cards notched in the intermediate field from dropping from the stack or pile of cards.

' In the present instance, the selective sort would result in the removal of all cards which are-inj dicative of the numbers 309.

The sorting rods or needles would be placed throughthe first and third fields, as before, and a' sorting rod would also be placed through the .10 perforation in the center field of the stack of cards. Accordingly, uponelevation of the card 'stack all cards which have been both notched and slotted in accordance with the 309 designation would drop down from the remaining cards a distance equal to the distance between the 0 and 1 perforations. The remaining cards :w ould stay in their elevated positions on the needles. Since the distance between the outer and inner rows of perforations ll, Ila is greater 'than the distance of the outer row of perforations I H from the card edge I2,the cards that have been selected, which, in the example shown in Fig. 3, have been slotted and notched to indicate the classification 309, would have dropped downwardly so their upper card edges H were disposed below the outer row of perforations H or below the sorting rod holes l6 outside of the digit fields l3 and adjacent the beveled corners I5 of the cards. Thereafter, a sorting rod or needle can be passed through the corner holes IS in the upper cards and the other sorting needles removed, which will allow all cards which have been notched and; slotted jingza ccprdance with the desired classification to 'dro'ip from the remainder of the stack, which is held in suspended position on the corner sorting rod.

In the. eventv that the number 307 were notched and slotted, instead of the number 309,

all cards in which the number '7 had been notched'would also drop from the stack, and such jcards would include those notched and slotted to the pattern of 308 and 309, as well as 307. Thereafter, the desired cards of 307 could be visually selected from the group or set of cards I that responded to the sort.

Another example of a selected classification is given in Fig. 4, in which the'number 30 'is notched or punched in a four digit field. If only the tens field were notched to indicate the number 30, selective sorting would be extremely difficult, since any other grouping of digits in the four fields that included the notching to the number 2 and number 1 perforations in the tens field 'would'respond'to the sort. By also slotting the 0 numbersin the digitfields that are not designated by any other number; only those cards in the-stack will drop downwardly a distance equal to the distanc'ebetween the inner and outer rows of perforations 'I la, I l'which have been slotted in the pattern 'of 0030"upon pass ing of the sorting rods or needles through the thousands, hundreds and unit-fields,=-a s 'well as through the 2 and 1 perforations inthe tens field. I v

Keypunch machines employed in 'connection with cards embodying the present invention are equipped to punch the 0 slot H in alldigit fields, unless a' key designating another figure depressed. For example, in the fo'ur digit fields illustrated in Fig. l, in which the number 30 is to be designated, if the card'is placed in the machine and operated without depress mg any keys whatever, the card field would be slotted in the '0 position in each of the four digit fields. If, however, the keys are first depressed" to designate the number 3 in the tens field, upo'n'operation, the machine will notch the card for the number 3 inthe tens field, thereby cancelling the 0 slot in that field, and slot all other digit fields for 0, as illustrated in Fig. 4'.

It is, thus, apparent that selective" sorting can be performed very readily in connection with the cards whose fields have the general number groupings indicated. Cards which have been notched and slotted in the manner described herein may also be rod or needle sorted sequentially by following the usual and established procedure. In performing such'sorting, the presence of ciphers in the code member's isig'nored, and, since the 0 designations are made on the cards with slots I1 which do notlextendto the edges [2 of the cards to.formnotche s,, the presence of the 0 slots does not interfere with the skilled in the art, since sorting rods are not placed through the field in which the 0" 8101; I1

2:5 reisei appears, in sequence sorting the presence or ab- '"sence of such slot makesnc difference, and the cards are sorted sequentially in the prior manner.

Fig. 5 illustrates a modified form of the invention, in which a more compact arrangement ofeperfo'rations or holes in each digit field is provided. "The outer row I lb of ,perforations in eachfield is indicative of thenhmbusflf" "2 and 4, whee the inner row ofgperforations in each'fieldinclude's aperforation I la forithe number? ,'ifi. alignment" with 'the n'umber: '1.perforati'on on a line perpendicular-to the eardedge I2, and a second perforation i la indicative of the number 7 on a line perpendicular to the card edge [2 and running through the center of the number 4 perforation. As is known, the numbers 7, 8 and "9 are obtained by a deep notch running from the card edge 12 to the number "7 perforation, the numbers 8 and 9 also being indicated by a shallow notch running from the card edge to the number 1 or number 2 perforations, as the case may be.

In the card illustrated in Fig. 5, the numbers 1 to 9, inclusive, are designated in each field by a shallow or a deep notch or notches I8 running from the card edge [2 to the particular perforation, or combination of perforations, while the number 0 is indicated by a slot I! extending between the 0 and number perforations, which slot does not extend to the edges l2 of the card. A stack of cards having the perforation pattern indicated in Fig. are sorted in the same general fashion as was described in connection with the other cards shown in the drawings, the number 0 not being ignored, but being designated in the fields where the digit is 0 by the slot I'l.

It is, accordingly, apparent that a comparatively simple card and manner of both sequence sorting and selective sorting have been provided, which enables, a grouping of numbers to be placed in each digit field adjacent the edge of the card, which is not only compactly arranged, but which numbers are relatively few, thus allowing a larger grouping of fields to be indicated along the edge of the card. The arrangement enables sequence sorting to be made rapidly in the usual manner, and also allows the same arrangement and grouping of the perforations to be used very readily in selective sorting, in which substantially only the desired cards responding to the selective sort are removed from the stack, requiring in some instances the visual removal of only a relatively small number of cards from the group or set of cards which responded to the sort.
